Relationship Between Atopy Patch Test with Foods and SCORAD
Background and Design: The relationship between food and atopic dermatitis (AD) is controversial. Atopy patch test (APT) gained prominence due to low specificity of “fresh prick tests” (FPT) with foods, commonly late occurrence of lesions in AD and, thus, the inconsistencies in anamneses, and being the provocative tests time consuming and risky, as well as due to the role of T lymphocytes in the pathophysiology of the disease. In this study, we investigated the relationship of APT and FPT made with food with SCORAD index assessing the disease severity.Materials and Methods: Forty-five children (21 males and 24 females) aged between 2-15 years who were diagnosed with AD in our outpatient clinic between May 2006 and May 2007 were included in the study. FPT and APT with eggs, milk and wheat flour were performed in all patients. The severity of illness was assessed using the SCORAD index. Statistical analysis was performed using SPSS version 11.0 for Windows. A p value of less than 0.05 was considered statistically significant

İzmir Körfezi güney kıyısı zeminleri için bir geoteknik deprem mühendisliği araştırması
Bu çalışma kapsamında, geoteknik deprem mühendisliği açısından, İzmir körfezinin güney kıyısın dinamik zemin davranışlarının araştırılması amaçlanmıştır. İzmir Fayı, İzmir şehir için en önemli deprem kaynağı olmuştur. Bu yüzden, RADIUS projesi kapsamında, 1999 yılında bir proje geliştirilmiştir. Bu proje, İzmir için İzmir fayının oluşturabileceği M=6,5 büyüklüğünde bir deprem senaryosunu içermektedir. Bu nedenle, 1977 İzmir (M = 5,3), 2003 Urla (M = 5,6) ve 2005 Urla (M = 5,9) depremine ait ivme kayıtlarının yanı sıra, İzmir Senaryo Depremi (M = 6,5) için de bu kayıtlar modifiye edilerek hesaplamalarda kullanılmıştır._x000B_Geoteknik veritabanı, araştırma alanı için daha önceden yapılmış olan çeşitli geoteknik raporlar kullanılarak kurulmuştur._x000B_Çalışmada, tek boyutlu dinamik zemin tepki analiz yöntemi kullanılmıştır. Eşdeğer doğrusal model, EERA bilgisayar programı (Bardet ve diğ., 2000) yardımıyla oluşturulmuş ve 1977 İzmir Depremi (M = 5,3) 2003 Urla Depremi (M = 5,6), 2005 Urla Depremi (M = 5,9) ve senaryoları için zemin tepki analizleri yapılmıştır ._x000B_Sıvılaşma analizleri, SPT-N değerlere bağlı olarak her sondaj ve derinlik için ayrı ayrı yapılmıştır.

In this thesis study it is aimed to investigate the dynamic behavior of soils of south coast of İzmir Bay in terms of Geotechnical Earthquake Engineering. İzmir Fault has been the most critical earthquake source for İzmir city. Thus, a project was evaluated by RADIUS team at 1999. This project includes an earthquake scenario which is due to İzmir fault. However, both the unique acceleration records which belongs to the 1977 İzmir Earthquake (M=5.3), 2003 Urla Earthquake (M=5.6) and 2005 Urla Earthquake (M=5.9), and İzmir Scenario Earthquake (M=6.5) that has been modified for İzmir Scenario Earthquake from the unique acceleration records have been used in computations._x000B_The geotechnical database has been established using various geotechnical reports that have been prepared on the investigation area._x000B_In the study, one dimensional site response analyses method has been used. The equivalent linear model and dynamic site response analyses have been performed by using the EERA computer program (Bardet et al., 2000) on 1977 Izmir Earthquake (M=5.3) 2003 Urla Earthquake (M=5.6), 2005 Urla Earthquake (M=5.9) and its scenario earthquakes._x000B_The liquefaction analyses based on the SPT-N values are made for each boring locations separately. The liquefaction risk computations of the study area are made by two different methods within upper 15 meter depth. The analyses are done for three different earthquakes and three scenario earthquakes. In the liquefaction analyses, the ?PGA? values are obtained from the site response analyses

Genişlemeli Bölgelerde Oluşan Transfer Fayların Gerinim Analizi: Mikropolar Teori ile Çıkarımlar
Transfer faults are generally identified as transversely oriented discrete faults linking normal fault segments in extensional tectonic settings. The presence of the transfer faults in fault networks provides displacement transfer between the normal faults. The role and tectonic significance of transfer faults in overall extensional deformation of the upper crust is however not known very well. Micropolar theory extended by J-2 plasticity facilitates evaluation of a deforming medium in which cataclastic flow takes place with respect to each component of deformation. In this study, a series of experiments based on the Micropolar theory are performed, using fault-slip patterns, to better understand interplay among dip angle of normal and transfer faults connecting to each other, angle of linkage, and extensional direction. Synthetic linkage cases are created systematically considering various orientation of both faults sharing common stretching direction.Our findings reveal that in orthogonal and oblique linkage cases, 3D strain field is mostly observed; a few cases exhibit plane strain. All cases are subjected to simple shearing. In cases of orthogonal linkage, extensional direction is predominantly oblique to the strike of the normal faults. Many of these cases have no block rotation (microrotation) independent from macrorotation. No particular relationship between changing dip amount of faults and direction of extension is observed. In cases of oblique linkage, (sub)orthogonal direction of extension appear in nearly half of experiments, especially those including normal faults dipping less than 60˚. The frequency of non-zero microrotation is seen apparently more than that in orthogonal linkage cases.The study represents that structural togetherness of the transfer and normal faults essentially can accommodate complete micropolar strain in a region. This further suggests that not only the normal faults but the transfer faults should also be considered as major primary structural elements in extending domains
Pediatric diffuse lipoblastomatosis of the foot - A case report and review of the literature
Diffuse lipoblastomatosis is a rare lipomatous tumor of infancy that derives from fetal-embryonal fat. It usually affects infants and children and presents as a superficial mass that extends from the subcutis to the underlying muscle in the upper or lower extremities. In spite of its benign nature, the tumor may behave in a locally aggressive manner and invade the surrounding tissues. A case of isolated diffuse lipoblastomatosis of a 5-year-old boy in the plantar aspect of his right foot that has not been documented in that area before is described. The clinical and radiological presentation and histologic evaluation of diffuse lipoblastomatosis are discussed, in order to make a differential diagnosis between this rare tumor and other soft tissue tumors. In addition, the treatment principles of the tumor are described. This case demonstrates that diffuse lipoblastomatosis can be difficult to diagnose without histologic evaluation and, once diagnosed, should be treated by adequate surgical excision in order to prevent recurrence

Determination of hydraulic performances of in line emitters
Damla sulama sistemlerinde sulama randımanı, damlatıcılardan çıkan debinin eşdeşliğine bağlıdır. İdeal olarak, bir sistemde bulunan tüm damlatıcılar eşit miktarda su dağıtmalıdırlar. Yapım farklılıkları, özünde eşit debilere sahip olması gereken damlatıcılar arasında debi farklılıkları görülmesine yol açan en önemli etkenlerden bir tanesidir. Bu çalışmada içten geçmeli damlatıcılardaki yapım farklılıkları ile değişik basınçlardaki debileri incelenmiştir. †retici firmalardan elde edilen değişik türden 12 damlatıcının altı ayrı işletme basıncında debileri ölçülmüştür. Debiler, basınç düzenleyici damlatıcılarda 50, 100, 150, 200, 250, 300 kPa ve basınç düzenleyicisiz damlatıcılarda ise 75, 100, 125, 150, 175 ve 200 kPa işletme basıncı değerlerinde ölçülmüştürr. Yapım, damlatıcı ve debi katsayıları elde edilerek, damlatıcıların akım rejimleri belirlenmiştir. Çalışma sonucu, 12 damlatıcıdan yalnızca 9 tanesinin öngörülen işletme basıncında ve üretici firmanın belirlediği debinin %10 alt ve üst sınırı içinde olduğu görülmüştür. Basınç düzenleyicisiz damlatıcıların tümünün debilerinin beklenenin çok üstünde olduğu gözlenmiştir. Basınç düzenleyici damlatıcıların düzenleyicisiz olanlara gšre daha yüksek yapım katsayılarına sahip oldukları ve bazılarının basınç değişimlerine az da olsa duyarlı oldukları görülmüştür.The efficiency of trickle irrigation systems depends directly on the uniformity with which water is discharged from the emission devices throughout the system. Ideally, all emitters in the system should discharge equal amounts of water. One major cause of flow rate difference between two identical emitters from the same manufacturer is the manufacturing variation. In this study, manufacturers rated discharges and coefficient of manufacturing variation values were compared with tested values for various in-line emitters. Discharge rates from 12 different types of trickle irrigation emitters were collected at six different operating pressure levels. Pressure compensating emitters were tested at 50, 100, 150, 200, 250, and 300 kPa. Non-pressure compensating emitters were tested at 75, 100, 125, 150, 175 and 200 kPa. Coefficient of manufacturing variation, emitter exponent and discharge exponent values were evaluated to determine the flow regime of each emitter. At the suggested operating pressure only nine of the twelve emitters had flow rates within 10% to those claimed by the manufacturers. All the noncompensating emitters had flow rates much higher than expected. Measured values of coefficient of manufacturing variation were higher for compensating emitters, and unexpectedly they were slightly sensitive to pressure differences
